Scriptaculous Autocomplete Page Jump Using Arrow Keys

Good find Jason Gill!

I implemented a script.aculo.us Ajax.Autocompleter only to find a serious behavioral problem where the use of the arrow keys would cause the page to jump all over.

Jason found a nice and easy way to tame the wild beast.

The only negative to the fix is that the original controls.js source code needs to be modified, but until the bug is fixed in the main source stream, that is just fine with me. The only gotcha will be if the next update to script.aculo.us does not contain a fix for this problem, trying to remember that the source code needs to be modfied. This gotcha will still be an issue if an external fix would make a modification to the Autocompleter.Base for the patch would need to be removed when the code base is finally fixed. So it boils down to six of one or half a dozen of another; so my choice is to go with what Jason has since it works.

Once again, great find Jason!
